  • Bytedance Proposes Faster Linux Inter-Process Communication With "Run Process As Library"

    Jump

  • The gist is that a system call is introduced to go into the PCB and change the Effective UID of a process. Security is ensured by a processor MPK which is a CPU provided guard so that a {Process, Library} has only a restricted set of Effective UIDs it can switch to. This operations is supposed to use 30 to 50 clock cycles. So entry + exit is supposed to be done in 100 cycles. This is considered low overhead context switch compared to the traditional context switch on Linux for slower IPCs. They don't do a comparison against iouring, or simply multi-threaded process.

  • Git without a forge

    Jump

  • well yes... that's what one expects when they go DIY.

  • Exploiting Undefined Behavior in C/C++ Programs for Optimization: A Study on the Performance Impact

    Jump

  • or simply use a well designed programming language.

  • Python Performance: Why 'if not list' is 2x Faster Than Using len()

    Jump

  • lol this whole article and this thread is a bunch of bikeshedding I haven't had the privilege of enduring in some weeks.

  • We're cooked y'all 🤣

    Jump

  • THAT is the message you took from all this? What you're going to root for the smug ignorant asshole?

  • Lenovo now ship with Fedora

    Jump

  • probably for the labour it takes to do the OEM install and verify that everything is up to date and works.. like audio and multi-monitor.

  • Vibe Coding is not an excuse for low-quality work

    Jump

  • I often compare vibe coding to lord of the rings. Saruman blocks the fellowship's path with difficult challenges. So too does solving hard problems in programming. So Gandalf decides they will take the mines of moria (vibe coding). He knows better but does so anyway. The rest of the fellowship naively follows him down (junior devs). Most of the path is just minor hiccups and the juniors fumbling around. But they get to a certain point and things start to get too heated. The hordes of goblins being the bugs introduced by the LLM as they keep changing the code via different prompts. Then they inevitably awaken the Balrog.. the monstrous Complexity Demon that was brewing behind the vibe coding sunshine and roses.

  • Arch Says Goodbye to Redis, Adopts Valkey

    Jump

  • the arch maintainers are not terminally online like some of us.

  • Replace Your Regular Linux Commands With These Better Alternatives

    Jump

  • you have to install a nerd font i guess. nerd-fonts dot com.

  • Replace Your Regular Linux Commands With These Better Alternatives

    Jump

  • 3rd thing: these tools may not be available on the remote server at your company. so you don't want to stumble on the commands (aliases exist but the outputs are wildly different)

  • No Connection, No Flush

    Jump

  • We used to be able to do multiplayer only without the need for official servers.

  • No Connection, No Flush

    Jump

  • it's a bit of a straw man from your side to act like the discussion is about multiplayer when we are discussing about single player campaign based RPGs or about multiplayer when the company deliberately shuts it down in favour of a new version that just milks players for more money; or about toasters that definitely don't need internet connection to function.

  • How do you know if you are overengineering? Specific example in mind

    Jump

  • Thinking you can even prevent all unkowns is a foolish endeavor. Only work on solving the problem at hand. Why would I think about some future requirement and lose sleep over it? That's the PM and sales team headache! Or think of it another way... you haven't yet reached the bridge yet but you're already thinking you need rope for the imagined bridge collapse.

    All you can do with the present is make it relatively easier for your future self. Avoid complexity (thanks grug brained programmer!), don't tie yourself into knots and back yourself in corners (keep the code readable, testable and simple. This means minimal external dependencies, lose coupling but good coherence, and avoiding reinventing solution to difficult to solve problem)

    some of these goals seem contradictory but you have to apply them to a specific problem and the objective of solving the problem (why are you solving this problem?). For instance, for crypto the advice of avoiding reinventing the solution takes precedence to minimal dependencies one because your objective is security which is important to get right without tolerance for bugs.

  • I am really considering moving from Arch to Fedora. What's your experience with this?

    Jump

  • I have never had luck with stability with fedora. But this was 5 years ago. Might try that.

  • Raspberry Pi's maiden results may cause a ripple in 'year of transition', says bank

    Jump

  • these morons are going to realize one can't do any kind of training they assume should be trivial on an SBC like the PI. Then the stock is going to crash and we will be left with a ruined Raspberry Pi company.

  • How much did your current mechanical keyboard cost?

    Jump

  • 7000

  • Redis lost most of its external contributors after license change

    Jump

  • don't like that big companies don't want to pay for technology even if it's chump change

  • The Typewriter Is a Wooden Distraction-Free "WriterDeck" Powered by a Raspberry Pi 3

    Jump

  • hate to be that guy but the product itself is a distraction since most people just write on their laptops or desktops. If you want distraction free you can always use pen(cil) and paper.

  • No Connection, No Flush

    Jump

  • that's the company's problem. They made it too complicated.
